DRAWING-TABLE.

SPECIFICATION forming part of Letters Patent N0, 266,099, dated October17, 1882,

Application filed February 13, 1882.

To all whom it may concern Be it known that I, EDWIN O. OLEAVEs, acitizen of the United States, residing at (Jot-tland, in the county ofCortland and State of New York, have invented certain new and usefulImprovements in Drawing-Tables; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had tothe accompanying drawings. and to theletters or figures of reference marked thereon, which form a part ofthis specification.

The object of this invention is to provide a light and substantial tablefor drawing, writing, or studying purposes, and so constructed that whennot in use it can be folded so as to occupy but little space, and whichshall also combine the following important features: first, anadjustable top that can be used in a horizontal position or be readilyinclined at to the shelf and adjustable, so that the light may fall uponthe ohjectsfrom any side, as desired; fourth, a tray for holding drawingor writing materials. These objects may be attained by methodsillustrated in the accompanying drawings, in which- Figure 1 is a frontelevation of the table; Fig. 2, a rear elevation; Fig. 3, a verticalsection of the table on the line 1 2; Fig. 4., an enlarged view of apart of the upper portion of Fig. 3, showing the tray, the shelf in avertical position, and the spring or clamp for bolding in position thechart or figure to be drawn; Fig. 5, a rear view of the table, showing amodification in the legs as given in Fig. 2; Fig. 6, a side elevation ofthe table, as shown in Fig. 5; Fig. 7, a side view of the table as itappears when folded; Fig. 8, an enlarged view of a portion of the shelf,showing the method of securing the hook; Fig. 9, a perspective view ofthe table and screen. Figs. 10, 11, 12, 13, 14, 15, and 16 are detailedviews of the construction of my device.

(N0 model.)

Similar letters refer to similar parts throughout the several views.

The front and back legs,'A A B B, of the table are formed of twocross-pieces halved together, and strengthened by metallic plates ca,which are screwed onto the outside of the legs. The legs are hingedtogether at the top It IL, and are prevented from opening too wide orfrom closing when in use by the toggle-joint E, the ends of which areheld by a pin passing through the double ears 0 0, attached to theplates to a. In place of the rear legs, B B, a single leg, B, Fig. 5,with two arms, I) I), at its upper extremity, can be substituted, itdesired. The upper portion of the leg can be strengthened by the platea, the leg B to be hinged with the legs A A at h h, and to be held inposition by the toggle-joint E, which can be attached to the inner sideof the leg B, Fig. 6.

The top 0 is kept from warping by means of the cleatsN N, and is hingedator near the upper extremities of the front legs, A A. Any hinge willanswer, though the hook-and-eye is preferable on account of itssimplicity and the ease of its application. The top is held in itsposition, either level or inclined, by a rod, F, one end of which isattached to the under side of the top and the other end, passing throughthe loop I) at the lower extremity of the plate a, is secured by any ofthe common devices, as the set-screw, the eccentric, or, as shown inFigs. 1 and 3, by being notched and catching in the loop I). By havingother hooks placed at different points, as at 006 e, on the legs andeyes in corresponding positions in the edge of the top the height of thetable can be easily changed.

The shelf D, which can be used for holding or supporting models orfigures to be drawn, is hinged at or near the upper extremities of theback legs, B B. Across the under side of the shelf is a rib or cleat, H.The shelf is held in its different positions by the hook G, one endbeing fastened to the plate a atL and the other extremity hooking intothe hole a or n in the rib H, according as it is desired to bring theshelf into a horizontal or vertical position. To prevent the hookGfrombeing accidentally unhooked from the shelf D, it can be secured by meansof the spring P, Fig.8. the hook G is notched and pointed, and afterpassing through the hole a or a in the rib II it passes through a holein the spring P,which catches in the notch at the end of the hook. Anyspring, button, or catch that will secure the hook will answer thepurpose. Attached to the front edge of the shelf are two or more thinmetallic pieces, a: It, Figs. 4 and 9, to be used, when the shelf is ina vertical position, as rests or supports for the cards or platescontaining the figures to be copied. These supports have one edge turnedup to form a lip to prevent the cards or plates from slipping off, andare attached to the shelf byscrews or pins, which permit them to beturned, when not in use, so as to coincide with the edge of the shelf,the lip falling into a groove provided for that purpose.

The charts or figures to be drawn can be held in position by thespring-clamps J J, Fig. 4. The clamp consists of a thin metallic plateor disk, at, with a short stem, 1', that passes through the shelf and isfastened to the thumbpiece 7.. The hole through which the stem passes isenlarged on the back side of the shelf to receive a spiral spring, 2',and also the thumb piece h when compressed, as in J. ly pressing on thethumb-piece 70 the disk at is raised from the shelf, so that the card orpaper or whatever is to beheld can he slipped underit, when, by removingthe pressure, it will' be held in position by the action of the springi.

Serious dilliculty is often experienced in drawing from models andobjects, especially in studying them in variouslights and shades, byreason of cross-lights, and the dillicultyin causing the direct light tofall wholly upon one side of the object or objects to be shaded. Toovercome this difficulty, an adj ustablc screen, T, Fig. S), isprovided, which can be readily attached to the corners of the shelf 1).The screen maybe made of cloth, paper, or any suitable material, and isfastened at the ends e 'U to wooden or metallic rods, which can be heldin position by entering holes ma'inthe corners of the shelf. Similarrods, qq, detached from the screen, are placed at the corners z .2,around which the screen passes, thus inclosing three sides of the shelf1). \Vhen desirable to inclose only two sides the rod q can be removed,and the rod 'v be placed in its posi-' tion, the surplus screen to bewound around the rod 0.. By changing the position of the rods the lightcan be caused to fall from either side, as desired. Between the upperextremities of the legs A A B B, Figs. -land 9, is

scam

The end of I placed a tray, S, for holding drawing or writing materials.The trayis attached at its ends by screws or pins t t. to the legs. Thefront or back pins or screws work in slots to allow the closing of thetable. \Vhcn not in use the table can be folded, as shown in Fi .7, andfor convenience in transportation, if desirable, the legs AA B B B canbe hinged at 0 0 0, and fastened by means of a spring or hook at f, whenin use, and when folded be broughtinto the position of A AB (shown inFigs. land 5) and held there by the springs or catches y g near theupper extremities of the legs.

\Vhat I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. A drawing, writing, and study table having hinge folding legs heldapart by'togglejoint, said legs being adjustable, combined with theadjustable top and shelf, hinged at one edge, and supported respectivelyby the rods F and G, substantially as specified.

2. The combination, in a drawing-table, ot" the adjustable top U and rodF, the shelf 1), screen, and rod (I, substantially as and t'orthepurpose specilied.

3. A drawing, writing, and study tablehaving hinge folding legs heldapart by a togglejoint, and the tray S, secured between said legs bymeans of pins or screws, combined with the adjustable hinged top andshelf, and the rods F and Gr,substantially as and forthepurposes setforth.

4. The adj ustableshelt'D,having perforated lug H, combined with thehooked rod G and spring locking-rod l, as and for the purposes setforth.

5. In a drawing, writing, and study table, the combination of theadjustable folding legs, the shelf D, the hook G, and adjustable rest20, all substantially as and for the purposes set forth.

6. In a drawing, writing, or study table,the combination oftheadjustable folding legs, the adjustable shelf I), the hook Gr,adjustable rest to, and clamp J, all substantially as and for thepurposes set forth.

7. In a drawing, writing, or study table, the combinationof theadjustable folding legs, the shelfD, the adjustable screen T, andmovable rods (1 0, all substantially as and for the purposes set forth.
